Application filed October 3. 1912. Serial No. 724,632.

To all whom it may concern.

Be it known that I, JOHN H. CAS'LONA, a citizen of the United States, residing at Gulfport, in the county of Harrison and State of Mississippi, have invented new and useful Improvements in Extracting Apparatus, 0t which the following is a specification.

This invention relates to an apparatus for extracting turpentine and other essential oils and rosin from wood, and particularly to a horizontal type of apparatus of this character designed for use in connection with steam and a volatile solvent in the ex tracting operation, the primary object of the invention being to rovide an organization of parts whereby tie material may be etfi-' ciently treated and the apparatus quickly and conveniently charged and emptied.

A. further object of the invention is to provide an extracting apparatus which is simple of construction, economical in operation and adapted to enable a maximum amount of highly pure products to be ob tained from a given amount of material.

The invention consists of the features of construct-ion, combination and arraiigement of parts hereinafter fully described and claimed. reference being had to the accompanying drawings, in which Figure 1 is a side elevation, partially in longitudinal section, of an extracting appa atus embodying my invention. Fig. 2 is a sectional front elevgtion o l the line 22 of Fig. 1. Fig. 3 is a vertica transverse section on the line 3-3 of Fig. 1.

In carrying my invention into practice, I provide an outer elongated horizontal casing l, preferably square or of suitable rectangw lar form in cross section and sustained in any desired manner. This casing is preferably closed at its rear end 2 and open at its front end, which latter is provided with an abutment flange 3. A door 4 is employed to close the said open front end of the casing and is hinged at one side thereto, as shown at 5, for swinging movement in a horizontal plane, which door carries a gasket 6 to engage the flange 3 and tightly seal the joint when the door is in closed position. The edges of th door are provided with notches or recesses 7 to receive swingbolts 8 pivoted to brackets 9 on the casing, said bolts being equipped with wing nuts 10, whereby the door may be firmly held closed.

The casing 1 is provided at its top with a coil 16 is arranged within dome outlet 11 for the discharge Of the volatile products, which dome communicates with a discharge pipe 12 having a controlling valve 13, said pipe being designed. to convey the, volatile products ton suitable condenser. The casing is also provided in its bottom with a pipe-14: having a'controlling valve 15 for the discharge of the rosin and any water of condensation from the steam which may be present therewith. A perforated horizontal longitudinal pipe or the upper portion of the casing for the supply of a volatile solvent to the material. under treatment. This coil communicates with a solvent supply pipe 17 having a controlling valve 18. A heating coil 19 is arranged horizontally and longitudinally within the bottom of the casing for supplying heat to maintain a de sired temperature therein, said pipe as disposed also serving to keep the resin in a liquefied state for ready discharge. ihis' coil is supplied with steam through a pipe 20 having a controlling valve 21 and. is provided with a drain pipe 22 having a controlling-valve Through this pipe any water of condensation in the coil may be discharged, and during tlieentracting operation the valve 23 may be leiit open to a desired degree in order to secure a proper cir culation of the steam or heating agent.

Arranged upon the sides of the casing above the coil 19 are track rails 24: which are adapted to support a car or carriage cons prising end brackets Qt, longitudinal rails :26 and front and rear transverse shafts or axles 27, the last named carrying wheels or rollers 28 to run upon said rails, Extending through and journaled in the brackets is a horizontal steam supply pipe 29, which is suitably closed at its rear end and at its front end extends beyond the adjacent bracket and carries a llXQfl clamping plate 30 and a gasket 31 secured thereto by bolts 32. These bolts 32 are adapted to be passed through openings in the door when the latter is closed and to be clamped thereto by outer wing nuts 33, whereby the car will be held in fixed relation to the door when the. casing is sealed for action. The door is also provided with an opening for the reception of a steam supply pipe bar ing a controlling valve 35 and to which is attachedfl t hose 36 leading from a suitable source of steam supply. The pipe 34 is fixed 1 to and movable with the door and 1s adapc inc ed to abut at its inner end against the adja cent end of the pipe 29 when the door is closed and to be held in steam-tight connection thei'ewith by the plate 30 and gasket 31 when the wing nuts 33 are drawn up, thus enabling steam to be supplied to the pipe 29.

Supported by the p'pe 29 and extending longitudinally between the brackets 25 of the car is an elongated rectangular basket or cage 37 to receive the comminuted wood, said cage being open at the top and having its bottom, sides and ends perforated for the discharge of the liberated volatile products. The cage is fixed to the pipe 29 and properly balanced to maintain a normal horizontal position. The basket or cage is thus supported by the car and may he run into and out of the casing on the track rails 24 when the door 4. is open.

In. operation, the cage is filled on the exlerior with a charge of comminuted Wood and then run into the casing and the door 4 then closed to seal the casing and connect the pipes 29 and 36. Steam is then ad mitted to the perforated cage through the pipe 29 and to the coil 19 through the pipe 20. The steam issuing through the perforations of the pipe 29 permeates-the mass of comminuted wogd throughout and liberates the major portion of the volatile constituents and rosin therefrom, the vapors discharging through the pipe 12, while the rosin gravitatcs to the bottom of the casing, from which it is subsequently withdrawn through the pipe 14. During the extracting operation the coil 19 keeps the rosin in a fluid condition for ready discharge and acts in conjunction with the steam supplied through the pipe 29 to maintain the interior at the required temperature. After the major portion of the volatile constituents and rosin has been driven from the wood, a solvent is admitted through the pipe 16 and percolates through the mass of wood to free the remaining volatile constituents and rosin and facilitate the discharge of the latter. Phi s solvent is vaporized by the internal heat andpasses off with the volatile products through the pipe 12 to a suitable condenser for separation. After the products have been fully extracted the supply of steam is cut oil, the door 4 swung open and the car supporting the cage withdrawn from i the casing and run upon a suitable exterior track (not shown) and the cage then tilted upon the pipe 29 as an axis to dump the refuse wood. The cage may then be rwfilled and run back into the casing for a repetition of the above described operation or another cage inserted in its place, the construction described permitting the material to be readily and conveniently entered and withdrawn and the operation. as a whole carried out at the expenditure of a minimum amount of time and labor.

I claim 1. An extractor comprising a casing open at an end thereof, track rails upon the interior of the casing, a car insertible and removable through the open end of the casing through said door.

2. An extractor including a casing open at an'end thereof, track rails upon the in- ..terior of the casing, a car insertible and removable through the open end of the casing and adaptedto rest and travel upon said rails, said car having uprights at the ends thereof, a perforated pipe extending longitudinally of the car and supported by said uprights, a cage mounted to tilt laterally upon the pipe as an axis having an open top and perforated bottom, side and end walls, means for heating the interior of the casing, a door for closing the open end of the casing, and means for connecting the perforated pipe with a supply conductor through said door.
